The pH of our buffer is equal to 4.76 (the ‘pKa’ of acetic acid) plus the log of 0.4 divided by 0.4, which equals 4.76 plus the log of 1. WebBuffers are broadly divided into two types – acidic and alkaline buffer solutions. Acidic buffers are solutions that have a pH below 7 and contain a weak acid and one of its salts. For example, a mixture of acetic acid and sodium acetate acts as a buffer solution with a pH of about 4.75. Alkaline buffers, on the other hand, have a pH above 7 ... proline body and chassis 545 river dr 07407
